# 🔧 Installation
The code is tested on Python 3.10.0, CUDA 12.4 and H100.
```
./env_setup.sh fastvideo
```
To try Sliding Tile Attention (optional), please follow the instruction in [here](#sta-installation) to install STA.

# FastHunyuan
## Inference FastHunyuan on single RTX4090
We now support NF4 and LLM-INT8 quantized inference using BitsAndBytes for FastHunyuan. With NF4 quantization, inference can be performed on a single RTX 4090 GPU, requiring just 20GB of VRAM.
```bash
# Download the model weight
python scripts/huggingface/download_hf.py --repo_id=FastVideo/FastHunyuan-diffusers --local_dir=data/FastHunyuan-diffusers --repo_type=model
# CLI inference
bash scripts/inference/inference_hunyuan_hf_quantization.sh
```
For more information about the VRAM requirements for BitsAndBytes quantization, please refer to the table below (timing measured on an H100 GPU):
For more information about the VRAM requirements for BitsAndBytes quantization, please refer to the table below (timing measured on an H100 GPU):
| Configuration | Memory to Init Transformer | Peak Memory After Init Pipeline (Denoise) | Diffusion Time | End-to-End Time |
|--------------------------------|----------------------------|--------------------------------------------|----------------|-----------------|
| BF16 + Pipeline CPU Offload | 23.883G | 33.744G | 81s | 121.5s |
| INT8 + Pipeline CPU Offload | 13.911G | 27.979G | 88s | 116.7s |
| NF4 + Pipeline CPU Offload | 9.453G | 19.26G | 78s | 114.5s |
For improved quality in generated videos, we recommend using a GPU with 80GB of memory to run the BF16 model with the original Hunyuan pipeline. To execute the inference, use the following section:

python scripts/huggingface/download_hf.py --repo_id=FastVideo/FastHunyuan --local_dir=data/FastHunyuan --repo_type=model
# CLI inference

```
You can also inference FastHunyuan in the [official Hunyuan github](https://github.com/Tencent/HunyuanVideo).

# HunyuanVideo
## Inference HunyuanVideo with Sliding Tile Attention
First, download the model:
```bash
python scripts/huggingface/download_hf.py --repo_id=FastVideo/hunyuan --local_dir=data/hunyuan --repo_type=model
```
We provide two examples in the following script to run inference with STA + [TeaCache](https://github.com/ali-vilab/TeaCache) and STA only.
```bash
sh scripts/inference/inference_hunyuan_STA.sh
```
## Video Demos using STA + Teacache
Visit our [demo website](https://fast-video.github.io/) to explore our complete collection of examples. We shorten a single video generation process from 945s to 317s on H100.

Use the following scripts to run inference for StepVideo. When using STA for inference, the generated videos will have dimensions of 204×768×768 (currently, this is the only supported shape).
